I have a slightly non-standard setup - I'm running Outlook 2007 in an
Exchange environment.  My "primary" Inbox runs via my company and is setup on
our Exchange server and cached locally on my PC.  BUT, I also have a second
.pst file with my personal POP3 email - which comes in thru my primary inbox
and via Outlook Rules is directed to my Inbox on my local .pst file.

I use my Exchange calender exclusively, but I do periodically backup / copy
this calendar to the calendar folder on my local .pst file.  This gives me a
backup in case something happens to my primary calendar (also do this for my
contacts).  The problem is that my Tasks and Meeting Reminders show up in
duplicate every time an event is 15 minutes out.  It's not a problem, just a
little annoying.  Is there any way to tell Outlook to suppress the events in
my "secondary / backup" calendar on my local .pst file?  (hope I explained
this OK).  I'm more of an Outlook Power User and haven't been able to figger
this out.
